Description
Technical field
The utility model belongs to the cannot-harm-detection device technical field, is specifically related to a kind of pipeline girth weld air-flow the cannot-harm-detection device.
Background technology
Pipeline is a kind of range of application material very widely, it is widely used in industrial or agricultural field, foundation construction field and our daily life, water pipe, gas piping common in such as our daily life, say the petroleum pipe line in industrial circle, natural gas line etc. for another example.Whether the girth joint quality of pipeline is just related to pipeline closely knit, therefore traditional method of inspection is by stifled for the two ends of pipeline real, the gas of certain pressure is passed in pipeline, whole piece pipeline is immersed in the water, according to whether have in water emit bubble to judge whether pipeline closely knit, or water is poured in pipe, keep certain pressure and time, see and whether produce leakage.But this traditional method of inspection is very cumbersome.
Utility model content
The purpose of this utility model is solve above-mentioned technical matters and provide a kind of pipeline girth weld air-flow the cannot-harm-detection device.
For achieving the above object, the utility model adopts following technical scheme:
A kind of pipeline girth weld air-flow the cannot-harm-detection device, comprise one for being placed in the annular solid in tested pipeline, the central authorities of described annular solid are provided with an airflow opening, the outer wall of described annular solid has the first ring connected in star that the girth joint of tested pipeline can be surrounded from inner-walls of duct sealing, at least one circle Tiny pore hole is laid with along groove bottom annular in described first ring connected in star, described Tiny pore hole is connected by gas channel with described airflow opening, and described airflow opening connects a high-pressure air source by tracheae; On the outer wall of described tested pipeline, correspondence is provided with an annular ring, and the medial surface of annular ring has second annular groove that the sealing of the girth joint of tested pipeline can be surrounded from pipeline outer wall, and annular ring is provided with baroceptor.
Described annular solid and annular ring are made up of elastomeric material.
Annular ring comprises two semicircle circles, and one end of described two semicircle circles is flexibly connected, the other end is locked by quick detach screw rod.
The utility model is by comprising one for being placed in the annular solid in tested pipeline, the central authorities of described annular solid are provided with an airflow opening, the outer wall of described annular solid has the first ring connected in star that the girth joint of tested pipeline can be surrounded from inner-walls of duct sealing, at least one circle Tiny pore hole is laid with along groove bottom annular in described first ring connected in star, described Tiny pore hole is connected by gas channel with described airflow opening, and described airflow opening connects a high-pressure air source by tracheae; On the outer wall of described tested pipeline, correspondence is provided with an annular ring, the medial surface of annular ring has second annular groove that the sealing of the girth joint of tested pipeline can be surrounded from pipeline outer wall, annular ring is provided with baroceptor, air-flow can be sprayed and pressurize a period of time by being honored as a queen by weld joint close in annular, the gaseous tension in outside seal space is detected by the baroceptor on outer annular circle, thus whether testing pipes weld seam welds intact, there is structure simple, the problem that detection efficiency is high.
Accompanying drawing explanation
Figure 1 shows that the structural representation of a kind of pipeline girth weld air-flow the cannot-harm-detection device that the utility model embodiment provides.
Embodiment
Below, in conjunction with example, substantive distinguishing features of the present utility model and advantage are further described, but the utility model is not limited to listed embodiment.
Shown in Figure 1, a kind of pipeline girth weld air-flow the cannot-harm-detection device, comprise one for being placed in the annular solid 3 in tested pipeline, the central authorities of described annular solid are provided with an airflow opening 4, the outer wall of described annular solid has the first ring connected in star 12 that the girth joint 2 of tested pipeline 1 can be surrounded from inner-walls of duct sealing, at least one circle Tiny pore hole is laid with along groove bottom annular in described first ring connected in star 12, described Tiny pore hole is connected by gas channel 5 with described airflow opening 4, described airflow opening connects a high-pressure air source 11 by the tracheae 10 connected by joint 9, on the outer wall of described tested pipeline, correspondence is provided with an annular ring 6, and the medial surface of annular ring has second annular groove 7 that the sealing of the girth joint of tested pipeline can be surrounded from pipeline outer wall, and annular ring is provided with baroceptor 8.
It should be noted that, described annular solid and annular ring are made up of elastomeric material.Adopt elastomeric material, this annular solid can be made to contact better with the sealing of pipeline with annular ring, thus make inwall produce the gas of enough pressure, outside can detect the subtle change of air pressure, thus whether closely knit, to detect welding quality if can better detect weld seam.
Further, annular ring 6 comprises two semicircle circles, and one end of described two semicircle circles is flexibly connected, the other end is locked by quick detach screw rod.By such design, this annular ring Fast Installation can be facilitated in girth joint 2 place, also realize quick-detachment, conveniently install and use.
The utility model is by comprising one for being placed in the annular solid in tested pipeline, the central authorities of described annular solid are provided with an airflow opening, the outer wall of described annular solid has the first ring connected in star that the girth joint of tested pipeline can be surrounded from inner-walls of duct sealing, at least one circle Tiny pore hole is laid with along groove bottom annular in described first ring connected in star, described Tiny pore hole is connected by gas channel with described airflow opening, and described airflow opening connects a high-pressure air source by tracheae; On the outer wall of described tested pipeline, correspondence is provided with an annular ring, the medial surface of annular ring has second annular groove that the sealing of the girth joint of tested pipeline can be surrounded from pipeline outer wall, annular ring is provided with baroceptor, air-flow can be sprayed and pressurize a period of time by being honored as a queen by weld joint close in annular, the gaseous tension in outside seal space is detected by the baroceptor on outer annular circle. thus whether testing pipes weld seam welds intact, there is structure simple, the problem that detection efficiency is high.
The above is only preferred implementation of the present utility model; it should be pointed out that for those skilled in the art, under the prerequisite not departing from the utility model principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
